World's Largest AI Model Repository Hugging Face Breached by Autonomous AI Agent

AI Security/Vulnerability

In an ironic twist, open-source artificial intelligence (AI) platform Hugging Face revealed that it was the victim of a hack perpetrated by an autonomous AI agent system. The company said it detected and responded to the incident targeting its production infrastructure earlier last week. "We identified unauthorized access to a limited set of internal datasets and to several credentials used by our services," the company said in a statement. While an investigation into the intrusion remains ongoing, Hugging Face said it has found no evidence that the AI agent tampered with public, user-facing models, datasets, or Spaces, and its own software supply chain. The starting point of the attack was the data processing pipeline itself, with a malicious dataset abusing two code execution paths, viz., in its remote code dataset loader and a template injection in a dataset configuration, to run code on a processing worker.

New ENCFORGE Ransomware Targets AI Model Files in Langflow RCE Attack

Threat Intelligence/Vulnerability

Researchers at Sysdig have linked a second attack on the same Langflow server to JADEPUFFER , the AI-agent-driven operator it first documented earlier this month. The same operator has now been spotted deploying ENCFORGE , a new compiled Go ransomware designed to encrypt model weights, vector indexes, training datasets, and other AI infrastructure files across the host filesystem. The entry point did not change. Langflow versions before 1.3.0 expose the /api/v1/validate/code endpoint without authentication, allowing any remote attacker to execute arbitrary Python on the server. The flaw, CVE-2025-3248 , carries a CVSS score of 9.8 and has been in CISA's Known Exploited Vulnerabilities catalog since May 5, 2025. As The Hacker News reported earlier this month, the prior operation used throwaway Python code and MySQL's AES_ENCRYPT() function to encrypt and destroy data in Nacos (Alibaba's configuration server) and production databases. The new ENCFORGE payload re...

Critical SharePoint RCE CVE-2026-50522 Under Active Exploitation After Public PoC

Vulnerability/Web Security

A third SharePoint Server flaw patched by Microsoft as part of its Patch Tuesday update for July 2026 has come under active exploitation, per watchTowr . The vulnerability in question is CVE-2026-50522 (CVSS score: 9.8), a critical deserialization of untrusted data in Microsoft Office SharePoint that could allow an unauthorized attacker to execute code over a network. Microsoft credited DEVCORE researcher "splitline" with discovering and reporting the flaw. "In a network-based attack, an attacker authenticated as at least a Site Owner, could write arbitrary code to inject and execute code remotely on the SharePoint Server," Redmond said in an advisory released last week. "The attack vector is Network (AV:N) because this vulnerability is remotely exploitable and can be exploited from the internet. The attack complexity is Low (AC:L) because an attacker does not require significant prior knowledge of the system and can achieve repeatable success with the ...

Cl0p Affiliates Target Internet-Exposed PTC Windchill and FlexPLM with Unauthenticated RCE

Vulnerability/Ransomware

Threat actors linked to the Cl0p (aka Chubby Scorpius, FIN11, Graceful Spider, and Lace Tempest) ransomware campaign are exploiting flaws in internet-exposed PTC Windmill and FlexPLM deployments as part of a new data extortion campaign. "Attackers chain a pre-authentication information disclosure in the FlexPLM WSDL endpoint with a server-side flaw in the Windchill login servlet, enabling unauthenticated remote code execution and deployment of hex-named JSP web shells under /Windchill/login/," according to a new coordinated advisory released by Ransom-ISAC along with eCrime.ch and DEFUSED. Upon gaining an initial foothold, the attackers have been found to conduct file system enumeration, stage engineering/design data, and ultimately carry out double extortion data theft. Targets of the campaign include manufacturing, automotive, aerospace, and retail sectors. It's suspected that threat actors are exploiting CVE-2026-12569 (CVSS score: 9.3), a critical security fl...

OpenAI Agent Used Exposed Credentials Across Four Services During Hugging Face Breach

Artificial Intelligence/Vulnerability

OpenAI on Tuesday revealed the rogue artificial intelligence (AI) agent that escaped its sealed evaluation environment and broke into Hugging Face's production environment also hacked multiple third-party accounts and services as part of the attack. The latest disclosure shows that the security incident, which stemmed from an internal security test, was more extensive in scope than previously thought. The AI company said its ongoing review of the incident revealed a "small number of cases" where the models, including GPT-5.6 Sol and an "even more capable pre-release model," identified and used exposed credentials at the account-level on other publicly-available services. "This includes four accounts on four services as part of the Hugging Face incident (and a few accounts accessed as part of other evaluations)," it said. "One of these four accounts was used as an outbound relay and staging path, and another account was used for data st...

Public PoC Released for Exploited Check Point SmartConsole Authentication Bypass

Vulnerability/Enterprise Security

Cybersecurity researchers have shared additional technical details about a recently patched critical security flaw impacting Check Point Security Management Server and Multi-Domain Security Management Server (MDS) that has come under active exploitation in the wild. The vulnerability, tracked as CVE-2026-16232 (CVSS score: 9.3), is an authentication bypass in the SmartConsole login process that allows an unauthenticated remote attacker to obtain an application login token and use it to authenticate with full administrative privileges. "By leveraging CVE-2026-16232, an unauthenticated attacker can obtain an application login token, use this token to log in through SmartConsole with full administrator privileges, and modify the security policy or security configuration," Rapid7 said . Successful exploitation requires an attacker to have network access to the Management Server and a configuration that does not restrict Trusted Clients. Check Point has disclosed that it...

CISA Flags TeamCity CVE-2026-63077 RCE Flaw Under Active Exploitation in the Wild

Vulnerability/Enterprise Security

A newly patched security flaw impacting on-premise versions of JetBrains TeamCity has come under active exploitation in the wild , according to the U.S. Cybersecurity and Infrastructure Security Agency (CISA). The vulnerability in question is CVE-2026-63077 (CVSS score: 9.8), a case of deserialization of untrusted data that could allow an unauthenticated attacker with access to a TeamCity server to bypass authentication checks and execute arbitrary operating system commands with the privileges of the TeamCity server process. "JetBrains TeamCity contains a deserialization of untrusted data vulnerability that could allow unauthenticated remote code execution via the agent polling protocol," CISA said . According to JetBrains, the vulnerability can be exploited by an unauthenticated attacker via the TeamCity agent polling protocol to sidestep authentication checks and execute arbitrary operating system commands. The exact impact varies depending on the privileges grant...
